Silvan e006f67a89 feat(sihsim): more airplane thrust for a 30 deg climb and 20 m/s cruise ...

At 9000 RPM the propeller produced 4.6 N at trim airspeed while the model
needs about 5.3 N to hold 15 m/s level, so the plane could not sustain
trim airspeed at all.

Spin the same APC 8x6" propeller at 13000 RPM, which gives 11.3 N at trim
airspeed. The step is this large because prop wash over the tailplane and
the fin increases their local dynamic pressure, which eats roughly three
quarters of any added thrust.

Also raise the maximum climb rate, since a 30 deg climb at trim airspeed
needs 15 m/s * sin(30 deg) = 7.5 m/s and the default is 5 m/s.

Measured in SITL: 19.7 m/s at full throttle in near level flight (3 deg,
1 m/s climb). The thrust sustains a climb of over 30 deg, but reaching it
requires a steeper pitch than the takeoff and pitch limit defaults allow.
